\(\bullet \)  RGB-only Enc/Dec followed by depth estimation on the reconstructed images.
Fig REF d shows results for an indirect depth recovery approach. We estimate the depth map from a reconstructed RGB image as a post-processing step (The RGB image is reconstructed via an RGB-only framework with the perceptual features/similarity of [1]}).
This involves no training on depth data at all. This approach gives rise to poor depth reconstruction quality, indicated both visually and quantitatively in Fig REF .
